Objectives

Narrative objectives1

Among the evaluation of cerebral oxygenation indices by time-resolved-near-infrared spectroscopy (TD-NIRS) devices in routine medical care, this study targets cases that are measured before and after endovascular reperfusion therapy for cerebral infarction due to acute occlusion of the main cerebral artery, and aims to establish tissue reperfusion indices at the peripheral level of the brain before and after surgery

Developmental phase



Assessment

Primary outcomes

Relationship between TD-NIRS measurements and cases of functional independence (modified Rankin Scale 0-2) after 3 months in effective reperfusion cases

Key secondary outcomes

Relationship between TD-NIRS measurements and
Preoperative ischemia severity (NIHSS)
Ischemic core volume and penumbra volume and their ratio on preoperative CT perfusion imaging
Percentage of good collateral perfusion on preoperative CT angiography and cerebral angiography
Degree of reperfusion (expanded TICI grade) and presence of early venous drainage on cerebral angiography at the end of the procedure
Number of procedures performed in patients with complete reperfusion on cerebral angiography
Ischemic core volume and penumbra volume and their ratios in the immediate postoperative CT perfusion images
Infarct expansion within 24 hours after surgery
Symptomatic intracranial hemorrhage within 24 hours after surgery
Early improvement of neurological symptoms within 24 hours after surgery
